Yup... Vox has some sweet amps....
I picked up the Vox AD30VT a few years ago. I bought it to use at church and leave it there rather than dragging my Boogie in and out. It had a tube in it with hybrid circuitry and digital modeling of a bunch of amps. 3 preset channels all foot switchable made this a versatile little amp. I had a power knob on the back side to control the output amp section mater level while leaving the pre gain circuit alone.
I think I gave about $250 for the amp, cover, and the foot switch brand new. Guitar Center.... I sold it to a buddy after I stopped playing at the church and realized it was setting around here just collecting dust.
While it has a tube... the tube was not in the output section.
http://www.voxshowroom.com/uk/amp/ad30.html The amp sounded pretty nice and had some good tone. I used it to jam a few times where I could crank it and it hung in there pretty well volume wise...... and it could play quietly as well in a singing tone..... for use in the church setting. Compared to the Boogie.... there was no real comparison as the Boogie was exuding tone naturally and sounded much better in a side by side .... but the Vox was also about 1/5th the price of the Boogie. ( priced at Boogie prices for the equivalent Boogie amp in the stores now)
